This invention relates to fire extinguishers ofthe small portable type from which fire extinguishing liquid is ejected by means of a hand operated pump. FireV extinguishers of this type are provided with a nozzle iixed with reference to the liquid container, which container constitutes the body of the lire extinguishenandit is thereforefnecessary to hold `the 'containerain such a position that the streaml from the nozzle will play yupon the fire. Obviouslyfthisnecessitates holding the container in any.` of a great number of positions,fand` as the `liquid in the container flows to the lowermost part thereof, provision-mustvbe made for carrying liquid to the nozzle, whatever the position of the latter may be.`

Various devices have been produced whereby toautomatically connect the nozzle with thelowermost part of the container, which devices have been `more or` less successful and many thousands of such lire extinguishers have been sold and 'are now in use. lBut as fire extinguishers standfor long periods of time without being used,

, and since devices ofthe kind mentioned contain gravity operated mechanism,y valves, etc., which because of corrosiony or` even from mere disuse may be found inefficient,

if not positively inoperative, wh'en the fire extinguisher is needed, any means whereby such mechanism lcanbe eliminatedis a ldesideratum, .provided that by `such means the same, or practically the same,`useful results be'obtained. Moreover,as such mechanism is expensive -to construct, theV costof such fire extinguishers ztends to restrictthe number put into use, which is `another reasonl for a device without such mechanism being desirable.l I f tion is to produce a lire extinguisher which fulfillsY the requirements mentioned, kbut without gravity actuated mechanism. This 'is accomplished by" providing a; stationary 1924. Serial No. 696,429.

tain'er in-which the open end ofthe suction i tube is situated.y

Another object ofV my present invention is to lprovide a shut-off valve of improved construction whereby the nozzle may be closed, to prevent outflow'or evaporation of the fire extinguishing liquid, and another is to facilitate assembling of the parts, this being done by mounting all of the parts upon a single member of the container before said member'is united to other parts of the container, thus enabling all adjustments to-'be madewith the parts in full view of thel workman and in their ultimate relative positions. In the accompanying drawings illustratingmyinvention,

lIn certain respects my presentvalve mechanism resembles, although it isan improvement over, that shown in my application serially numbered 148,309. l Referring now nto Fig. l it will be seen that the container 10 constitutes the body of my lire extinguisher: Preferably, this container is made inl two pieces. rThe cylindri- `Fig. lis a longitudinal sectional view of Y l the mechanism of this fire extinguisher is mounted on the top, and when it is completed and adjusted rthe top is placed upon the body, the pump and other parts extending down into the body, or container, and the flange l2 vis soldered to the body. Since the parts are sustained entirely by the top andare not attached to the body, the body and top might be threadedrand screwed together.

Mounted on the top 1l is an air pump 13. As air pumps are well known and 'understood it will not be necessary to ydescribe this pump in detail. The top 11 is provided with4 a hollow boss l4intowhich the end of the tube that forms the cylinder of the pump. is inserted and soldered. In the center of the boss I4 is a hollow superboss 1,5, provided with a central hole through whichthe piston rod 16 of the pump passes. `On the outer end of the piston rod is mounted Vtheoperating handle 17. This handle has afhub 18 in which the piston; rod is secured-and the hub is provided with arecess 20, which, when the piston is in its innermost position, surrounds the vsuper-boss l5. A pinf21'is inserted crosswise in the piston rod within this recess, and the top. ofthe super-boss I5 is provided with two recesses 22 on opposite sides of the piston rod, ,through which the extending ends of the pin 21 pass when the piston is pushed to its innermost posi tion. Rotating the piston rod will then lock the rod in its innermost position.- At its inner end the piston rod is provided with a spring actuated plunger 23, therspring, not shown, tending to press the pistonrod outward a short distance.' One purpose of this plunger is to thrust the piston rod outward the moment the ends of the pin 2l register with the recesses 22. Thus when the handle is rotated torV the purpose of releasing it, the operator needs to use no care to turnl the handle `justthe proper distance. He simply turns it, and when the ends of the pin, regis.- ter with the recesses the piston is thrust out, feeling which the operator knows that the handle is unlocked and ready to be reciprocated. The plunger 23L also .serves as a. valve to seal the end of the pump cylinden-supplementing the regular spring actuated check valve,.not shown. The purpose o1" the air pump is to compress air inthe container,

` by which the fire extinguisher liquid is ejected. I shall now describe the valve mechanism and passages through which the liquid isdischarged.

Tnet-op 11 is made of sheet metal and the bossl'4 and the super-boss l5 aretormed by .pressing the sheet metaloutward. In like manner an inwardly extending collar 25 is formed on the top. The open end of a cylindrical valve casing 26 is secured to this boss, preferably with solder. This casing is threaded to receive a plug 27, having a head,

a suitable sealing gasket 28 being placed under the head. This plug has a longitudinal bore 29, about one-third of which, at its outer end, is of smaller diameter than the remainder of the bore. A plunger 30 slides inv thissmaller portion of the bore, and it has a head 3l in the larger part of the bore, which preventsv the plunger from falling out of the bore.. The inner end'of the plug,`

indicated byv the numeral 32, is arranged to act asia seat for a valve. At its inner end thevcasing 26 carries a tube 35. This tube connectsto. a standpipe formed integral with the casing, the standpipe extending some distanceinto the hollow part of the casing, its

end-,being finished to form the` Valve seat therein,;it resembles a piston, This member is so placed. inthe casing that the standpipe 'extends into the cup, and a cork or soft fibre disk 4l in the bottom of the cup is adapted to cooperate with the valve seat 36 andstop.l the flow ofy li'quidinto the casing. The outer bottom of the cup. is recessed to receive andl retain a cork or soft libre ring 42, while from the center of the bottom a small' stud 43 extends intoy the bore 29 of the plug 2;?. Surrounding the standpipe and conti-ned between the end of the casing and the disk 4:1 in the bottom of the cup is l a compression' spring 44, adapted to` move the valve member 40r to,Y and press the cork ring 42- aga-inst the seat 32. on the end of the plug 27. I-Ioused in the bore. 29 and surrounding the stud 43 is a second compression spring, 45. The inner end ofthis spring bears on thev head of the plunger 30, but a sealing disk 46, of cork, is interposed. Thisdisk. fits, the-bore 29 closely and assists in preventingleakage of liquid past the plunger. IlVhen the Vval-ve member moves to the seat 32 the spring 45, moved by the valve member, pushes the disk46 and the plunger toward` the; small end of the bore29.

See Fig. 3. Preferably, they length of the valve'member., The strengthzof the spring 45 is such that if the plunger 3() be pushed iso inward-the spring willfoverpower 1 the spring 44 and push the valve member from the seat 32 to the seat 36.' Seef'Fig. 1.

For the purpose of pushing in the plunger I provide a projection extending laterally from the hub 18 of the pump handle. This projection has a ilat face 51 which, when the handle is locked in with thebayt onet catch, holds ythe plunger in the posi@ tion it occupies in Fig. 1, That is,it`holds the valve closed. At each Aside the projection 50 is beveled away from the fiat. face 51, as at 52, so that after the handle is locked in, continued rotation of the handle brings one ofthese bevels 52 intoengagement vwith the end of the plungerand cams theplunger in.` The end of the plunger is rounded so as to facilitate thisaction.4 r In the center ofthe flat there isa slight depression 53,

into which thel end of the plunger may drop. The slight recession ofthe plungerdue to this is not suiiicient to impair'thef sealing value of the valve, while, because'y 'ofthe spring 45 being a rather powerful one, the plungerin this depression acts as a latch and holds the handle against accidental turning. v,

A port 60 is placed in the inner end of the valve casing, to which a tube 61 is connected. The other end of this tube is connected to the nozzle`62, which is Vrigidly-r mounted upon the iiange 12 of the container top. Referring to Fig. 2 it will be seenfthat thebore of the nozzle, represented by the 35 radial line 63, lies in la radial plane more than ninety degrees removed from the radial plane, represented by the line 64, in which lies the open end 37 of the tube 35. In this figure the end 37 of the tube is 'indicated with a small dotted circle placed close to the wall of the container. An opening is y'provided in the top for iilling the container with liquid, this opening being closed by a screw-plug 65. i5

I shall now describe the operation of my improved lire extinguisher: Graspin the container close to the'handle end wit one hand the operator seizes the pump handle with the other hand, unlocks the handle by Y5o rotating it approximately ninety degrees and proceeds to reciprocate the piston of the pump. 'Because of the nozzlebeing situated at the saine end of the -container as the pump handle, and because the nozzle throws a streamy perpendicular to thevaxisy ofthe container, it is most convenient for theoperator to lay the side" of the `container against his body, a short distance above his waist. In fact thatris the natural position into which to put this fire extinguisher. I-Ie naturally faces the fire, and with the container lying against his body the stream is projected straight away from him. Byrolling'the container he can direct vthe stream upward or downward. I have found that with the container :pressed to the bod'y'withv dency to Vassume the most eiiective position` for putting fortha vgiven muscular eiort.

In reciprocating the piston of the pump the l operatorY will naturally hold the Icontainer atan angle which will bring the piston into.

alignment withhis` fore arm, and there is a place on his body, above his waist, against which he will naturally press the container in Aorder to best'applyxthe necessary force for operatingthe pump; In View of=these facts I have located the nozzle in sucha position that with the container held in the left handf'and the ypump operated withlr the right, pointingthe nozzle awayfromthe oper'ator brings the' pump side of the container underneath. And it is 'in this side of the container that the inlet 37 of the'tube 35- is located. Referring to Fig. 2 it will jbefseen keeping in mind the lower end of' the vcontainer will be held several inches'lower than thehandle end, that by simply rollingthe container thel operator can direct the-stream overhead, yor almost under footy without raisling the inlet 37 more thanslightly above the lowermost part of the container.v Therefore, vsubstantially all of theliquid in the container can be thrown on a fire, regardless of the direction in whichthe stream must. be directed. k i

Theoretically the nozzle shouldbe-located `ninety ,degrees around from the radial plane Vin which the inlet lies. But practically this is notso; While it mightbe necessary, and even practicable,to stand directly under'a lire, 'one would lhardly stand directly over a fire he' was fighting. For this reason I locate the nozzle more than ninety degrees, may be yas many as one hundred and twenty, around from thev inlet,,thus reducingthe distance that the inlet 37 may have to be raised above the lowermost part of the container. In practice I have foundlthat having the stream leave the container-,inl a line perpendicular to theJOngitudinaIaX'is of the containeris satisfactory',butto enable the stream to be directed vertically.' upward.whil'e holding the lower end of the container at a lower level than theV handle end, the nozzlemay -be bored so that fthe streamv inclines slightkly-upward with' reference to-.thejlongit-udt nal 4anis of the container; say ten orifteen degrees above theperpendicular. l

vWfiththe nozzle located Vas shown, if the operator-Were to hold the container with his righthand andzpumprvvithrhis leftthe beelfim-i-i-iated by instruetions printed on the container; Qn the Yother hand, the reliabilitfy .of my improved device, due to its extreme simplicityand freedom lfrom mechanism Whose elficiencymay be impaired throughdisusemonby deterioratiomfar osetsv any possible failure of the device becauseofignorance ofthe operator.; Forr all tire extinguishers are subject to failure, more orV less complete, because of l ignorance 'or' v timidity on the part of theoperator.

'Oneofthe advantages ofv my improved valve mechanismis that when the v alve is open leakage of liquid past the plunger to the exterior of the container is prevented `by what. may be Acalled the secondary valve, namely, theY Vvalve i member 40 pressed against the endofthe plug 2:7 by the spring Thus amore effective seal is provided Ythan a, packing gland, While the frictionof the packing gland is eliminated. Another advantage of my present valve construction resides in the stream of liquidwhich flows into the valve casing, .being received inthe eup-y ofqthe valve member.v VThis directs 'the liquid back toward the port and, avoids any tendency Which the moving liquid mightf have to ,fio-W, past the vvalve member. vAnother advantage is that the liquid in the tube 35 presses against, the valve and tends tofpsupplement the. action ofthe spring i4 in opening the Valve. Still another advantage of my present'valve construction is the ease `With Whichthe V partsvcan be ref 2-7 1st removed.

moved for inspection or repair; `Unscrevv` and removing 'the AplugQ` releases all'of the parts :ofthe valve :and they may be drawn out ofthe casing 26 after the' plug As is VWell known, flow of liquid through a-'va'lve tends to disintegrate 'the-coluinn-or massi ofliquid; Asfitfis desirableV to expel the fire extinguishing liquid "in-La soli-d stream, thereby enabling thestreamto y'be comparativelylong tubular passage for the .liquid after it' has passed through the valve, thereby lgiving the liquid a chance'toifconsolidate.- I have also found solidity of the ejected strea'mvis-'pre'served by having .the liquid traverse Va" straight tube Whose axis coincides Withthat of the stream, forsome distance before it issues from1 thenozzle, say an inch orthereabout, Where the diameter of the` streaml is about one-sixteenth of anfinch. For these reasons I carry the liquid from -the linnerendv ofthe valve caising 2G by means off theicompar'atively long tube'l, landprovide astraight section of this tube to vconnect to' the nozzle, the axisv of thisv part of thetube and that vof the tube coinciding,v inpreference to taking a short cut'from' the valve casing tothe nozzle,
